Finding and evaluating randomised controlled trials in nursing conducted by Spanish research teams : A scoping review

Background/objectives: To identify and assess the main characteristics and the potential risk of bias of randomised controlled trials (RCTs) in nursing conducted by Spanish research teams. Methods: Scoping review of an electronic search in three major databases (date of search: October 2021). For the eligible studies, both descriptive data, and data to assess the potential risk of bias, were collected and analysed. Results: Of 3391 references retrieved, 199 were eligible. These RCTs were published in 122 journals, most of them in English (101, 82.1%) and were included in the Journal Citation Report (JCR) (107, 87.7%). Moreover, 32 (26.2%) of those included in the JCR were classified under nursing. Two thirds (81, 66.4%) of the journals followed the CONSORT guidelines. A total of 65 RCTs (33.7%) had a high overall risk of bias. Discussion: Most of the identified RCTs were published in journals not specific to nursing and in English language. Also, shortcomings in RCT design and reporting were observed despite recommendations to adhere the CONSORT guidelines. Conclusion: Comprehensive identification of RCTs in nursing may require searching in journals other than nursing-related. RCTs from Spanish research teams are more likely to be published in international journals published in English. CONSORT should be strongly advised to encourage proper design and reporting of RCTs.
